SELF-LIGHTINGGAS-BURNER.

SPECIFICATION forming part of Letters Patent N o.627,630 ,dated J une 27, 1899. Application filed November 26, 1897. Serial No. 659,872. (No model.)

To a/ZZ whom it may concern: y

Be it known that I, JOHN A. I/VILLIAMS, a citizen of the UnitedStates, residing at New York, (Brooklym) in the county of Kings and State of New York, have invented certain new and useful Improvements in Self-Lighting Gas-Burners, of which .the following is a specification.'

My invention relates to automatic gaslighters, the construction and advantages of which will be hereinafter set forth, reference being had to the accompanying drawings, in which- Figure lis a perspective view of the burner; Fig. 2, a similar View showing the lighting attachment in a different relation to the tip; Fig. 3, a view illustrating a modified form of construction, and Fig. 4 a side elevation showing the operation of the device.

Broadly stated, the object of my inventionO is to produce a self-lighting gas-burner, one which will automatically ignite the-gas and then through the heat 'produced by the flame withdraw the igniting substance from the path or line of the flame.

It comprises, in combination, a burner, a substance capable of igniting the gas by contact therewith, and a thermostatic device connected to the burner for holding the ignitin g substance.

Referring to the drawings, and particularly to Fig. 1, A indicates the burner, which may be of the ordinary construction, provided with a perforated lug or projection B, extending from one side thereof. Adj ustably mounted in said lug is a rod or bar C, carrying at its upper end acoil D. Said coil is composed of two strips of metal united to each other, the metals possessing different coefficients of expansion, so that when' the coil becomes heated it will unwind. The outer end Of the coil is extended upward and forms an arm E, to the upper end of which is secured a basket F, containing the substance capable of igniting the gas when coming in contact therewith.

While I have shown in the drawings what I term a basket, I do not desire to confine myself thereto, as any form of holder may be employed, and, in fact, a body of spongy asbestos impregnated with the igniting comrlriod of time.

-lation shown in the said figures the iiame will come into direct contact with the coil D and produce a very. quick action of the parts. The degree to which the Aflame will be interfered with by the coil under this form will be found to be 4very slight-that is, the flame Awill be cut by the coil, but will be found to reunite as soon as it passes beyond the same.

So soon as the gas isturned off thecoil will become cool and in so doing will draw the arm and its basket back into line with the opening in the tip of the burner, ready to again ignite the gas when it is turned on.

In Fig. 2 the opening in the tip is shown las standing in a line parallel with the coil, and

the coil is below the tip. The basket F or other igniting device is in this instance bent slightly over, so as to be in line withthe gas as it issues from the burner; but the action is substantially .the same as in the former construction.

In Fig. 3 I have shown two coils the arms of which are connected at the top and carry the igniting device. Under this construction the thermostatic coils may be made of lighter material than in the forms just alluded to.

The action, however, isthe same.

Iam aware that prior to my invention igniting substances have been held in line with the gas issuing from the burner; but in said devices.` the igniting substance has remained stationary, and consequently been enveloped by or kept in contact with the flame. Under such conditions the substan ce of necessity deteriorates, and it has been found that such devices will not work successfully for any pe- I am also aware that means have been employed whereby the igniting substance is normally out of the path of the flame and is designed to be manually brought in line therewith and afterward withdrawn through the agency of a spring, a weight, or the like. I am not aware, however, lthat previous to my invention any one has applied an igniting device to aburner in such manner that when the gas is ignited theigniting substance, which normally stands in thepath of the ame,will be automatically and positively withdrawn therefrom by the action of the flame or the heat generated thereby, and I desire to be understood as broadly claiming such idea.

The igniting material to be used may be any of the known compounds or substances which possess the property of absorbing and giving off oxygen and causing combustion, such as sponge platinum,platinu1n-black,and the like.

Means other than that shown may be employed for holding the coil.

Having thus described my invention, what I claim is- 1. In combination with a gas-burner, an iguiting substance therefor, and a thermostatic connection between said burner and the igniting substance.

2. In combination with a gas-burner, an igniting material adapted to ignite the gas by contact therewith, and a thermostatic device carrying said igniting material.

3. In combination with a gas-burner, an iguiting material adapted to ignite the gas by contact therewith, and means for supporting said ignitiug materia-l in line with the ame and for automatically withdrawing said material from the path of the ame when the gas is ignited.

4. In combination with a gas-burner, a thermostatic coil carried thereby, and an igniting material also carried by the coil and held in line with the openingin the burner, substaniially as and for the purpose described.

5. In combination with a gas-burner, a thermostatic coil adjustably' secured thereto, and an igniting material carried by said coil in line with the opening in the burner.

G. In combination with a gas-burner, athermostatic coil carried thereby, an arm extending from the free end of the coil, and an iguiting material carried by the upper end of said arm in line with the opening in the burner.

7. In combination with the burner A, lug

B secured thereto, arm C adjustably mounted within said lng, thermostatic coil D, arm E extending upwardly therefrom, and an igniting material carried bythe upper end of said arm.

S. In combination with a gas-burner, a thermostatic coil mounted thereon in line with the opening in the burner and adapted to come in contact with the ame as it issues therefrom, and an igniting material carried by the coil, substantially as described.

9. In combination with agas-burner, an igniting material adapted to ignite the gas by contact therewith, and means for supporting said material and drawing it into and out of alinement with the iiame, said means being controlled in its movement by the heat generated by the ame.

In witness whereof I hereunto set my'hand in the presence of two witnesses.

JOHN A. IVILLIAMS.
